Have you ever wondered why nearly all the top windsurfers use Fiberspar? Have you ever considered why most sailmakers design their sails on masts made by Fiberspar? There are other manufacturers that make carbon masts, but none of them feels like a Fiberspar.

A mast is moving all the time and gives the sail either a slow, heavy feel or a quick, responsive feel.... kind of like driving a car with loose steering versus driving a Porche. The secret to a fast windsurfing mast is the ability of the mast to stabilize the sail under excruciating loads- loads brought on by changes in wind strength, pumping for speed, vibration from chop, landing jumps, maneuvers and tricks. Each load inspires an appropriate response from the mast. How the mast reacts is called reflex response and is measured in units of speed.
Fiberspar masts are produced from single carbon thread that are carefully positioned in a patented process to provide the best strength to weight and maximize reflex response. For the same stiffness, the new Reflex 7000 Quick Tip, for example, returns to its original shape faster than all other masts. In windsurfing terms, this means that your sail will give you better acceleration and speed, at the same time offering better control. The development of windsurfing masts with the fastest reflex response has been a cornerstone of Fiberspar Technology since 1986. As one of the ways we quantify the impact of new designs, processes and materials, Fiberspar engineers constantly measure the reflex response of different masts with an electronic eye and oscilloscope. This test measures the speed at which the tip of the mast returns to center after deflected with a standard load.
The Reflex Indicator numbers (Reflex 3200, Reflex 4200, Reflex 4600, Reflex 7000) are proportional to the first mode of vibration of the mast, and the drag coefficient of the mast diameter, measured in milliHertz. Typical Reflex Indicator numbers for windsurfing masts range from 2000 mHz to 5000 mHz, and for the first time the 7000 mHz milestone has been broken!

No need to get hung up on the numbers, the higher the Reflex Indicator number, the faster the response time. The Reflex 7000 QT has more than ten percent higher reflex response than any other mast.
